Garrison Keillor has confirmed to the Associated Press that he was fired by Minnesota Public Radio over allegations of improper behavior.

The former host of radio show A Prairie Home Companion confirmed his dismissal while adding that the incident involved “a story that I think is more interesting and more complicated than the version MPR heard.”

Keiller, 75, retired as host of Prairie Home Companion in 2016, but still produces the syndicated radio show The Writer’s Almanac. The AP says Keiller is finishing a Lake Wobegon screenplay and a memoir about growing up in Minnesota.

“It’s some sort of poetic irony to be knocked off the air by a story, having told so many of them myself, but I’m 75 and don’t have any interest in arguing about this. And I cannot in conscience bring danger to a great organization I’ve worked hard for since 1969,” Keillor told the news organization.

The AP report includes confirmation from Minnesota Public Radio that it fired Keillor Wednesday following a single allegation of inappropriate behavior.

News of Keillor’s firing comes just days after he penned a column suggesting Al Franken should not resign from the Senate. The article was headlined “The absurdity of judging past actions by present standards.”
